SPECIFICATION forming part o Letters Patent No, 372,586, dated November l, 1887. Application filed February 24, 1887. Serial N o. 228,775. (No model.)

To all whom t may concern,.-

Be it known that I, EUGENE J. WILLIAMS, a citizen of the United States, residing at Springlield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Vapor-Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

tially, of a pipe which conducts the oil from a suitable reservoir and constitutes a retort in which the gas is generated, as also a burner located with such reference to the retort portion of the pipe that the latter is subjected to the intense heat of the darne rising from the former, and in providing said pipe with an oilsprayer located between the supply and the retort portion.

My invention further consists of a sprayingnipple having a stem which extends through it, and has a deilecting-head which shatters the small stream of oil into a fine spray.

In the accompanying drawings, forming a part of this specification, and on which like referenceletters indicate corresponding features, Figure 1 represents a partial sidel and sectional view of my improved burner; Fig. 2, an end View thereof; Fig. 3, a plan view. of the flame-spreader, and Fig. 4t sectional views of the pipe and spraying-nipple.

Letter A designates a metallic shell, preferably of substantially rectangular form, and constructed of cast-iron, and having in its upper portion a series of holes, through which the flames pass, while the intermediate metal deilects and holds the dames somewhat against the retort. Vhen this flame-spreader is placed in a stove lire-box, as the ordinary stove, and it is desired to hold the iiames to the front part of the stove, the damper B, composed of a plate of iron, is turned tothe position shown in Fig. 2 in full lines. yWhen it is desired to let the ilames pass to the rear of the stove and heat that portion, the plate is turned to the position shown in dotted lines. Ledges C serve to hold the plate in position, the same being-pivotally-mounted on lugs D.

A pipe, E, leads from a suitable reservoir, F, in which the oil is contained, to the dame` spreader A. Passing under, it is bent at G and carried a second time under the spreader, and forms the burner portion H of the pipe. Aseries of small holes is formed in the upper side of the burner H, through which the generated gases are emitted and at which points they are ignited.- A narrow and shallow trough, I, incloses the numerous apertures, and serves to collect anyoil that may pass out through the apertures before the gas has begun.

to be generated, as when first lighted.

A cut-off, J, is placed at a convenient part of the pipe E, and in proximity to the spreader a sprayer is placed within the pipe and constructed to spray the oil flowing through it into the portion K of the pipe which forms the retortor gas-generating chamber. This sprayer inthe present instance consists of a metallic plug or nipple, L, fitted snugly into the pipe, and having a tapering hole therethrough and a funnelshaped mouth at M. A small stem passes through the-tapering hole and is secured at one end of the nipple to a cross-piece, as at N, and provided with a conical head, O, against which the ne stream of oil forcibly strikes, and by whichl it is shattered into a iine spray. This spray issues into the retort K, and is converted into a combustible vapor or gas by the heat of the retort. The heat of the retort also raises the temperature of the gas generated and makes it eX- pand and more readily burn, and acts t0 super-heat it as the gas ows through the retort from the portion where it is essentially generated (near the left-hand end of the shell A`) across the saine and toward the burner. The lexpansion produces more heat from the same quantity of gas than would be produced if it were not superheated. I do not here allude so much to an increased intensity of heat, but more heat in point of time.

I desire to observe that I am aware that oilroo burners have been made in which the oil was heated as it passed on its way to the burner and was converted into a gas. In such instance, however, the oil was allowed to accumulate in quite :t body as distinguished from being,` sprayed. The spraying` process econoinizes in the consumption of the oil, enables the oil to be converted into gas quickly and at nlower heat, and prevents the obj ectionnble accumulation of sediment andother residuuin resulting' from vziporizing the oil when in a body. Vith my improvement these objec tions do not exist, as I have ascertained by repeated trials, and :in intense flame is produced und the spray is converted into gas nt zt much lower temperature, and therefore niuch sooner, than were the oil allowed to flow into the retort.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isv l. In en oilburner7 the combination, with a reservoir, a pipe leading therefrom having a cock, a portion forming n rctort,nnother portion forming :L burner having a series of perforations, nn d L trough thereon and located under the retort, of it ilmnevsprender located over the burner and inccsing thc retort, and a spraying-nipple within the pipe hnving a tapering hole and a stem with :i conical head.

2. In mi oil-burner7 the combinntiomwith a pipe one portion of which forms a retort, another portion of which extends beneath the retort portion and forms fi burner, and yet nnother portion of which Vforms :t conduit between the retort and the burner, of n hollow nipple and a flaring heed near the discharge end thereof to spray the oil, and located in the said pipe near the retort portion and opposite to the end of the retort away from the end which connects with the burner.

In testimony whereof I :ii'x my signature in presence of two witnesses.

Corrections in Letters Patent No. 372,586.

"k It is hereby certified that in Letters Patent No. 372,586, granted November l, 1887,

upon the application of Eugene J. Williams, of Springeld, Ohio, for an improvement in Vapor Stoves,77 an error appears in the `printed specification requiring correction, as follows: lll-lines 6 and 10, page l, the Words Vapor Stoves7 should be stricken out, and the Words YOil Burners inserted instead, and that the Letters Patent should be read with these corrections therein that the same mayr conform to the record of the case in the Patent Office. l

Signed, countersigned, and sealed this 6th day of December, A. D. 1887.
